TA-8566 REG: Mainstreaming Integrated Solid Waste Management in Asia Integrated Solid Waste Management Plan Buriram NovemberOctob 2015er 2016 Integrated SWM Plan Disclaimers This Integrated Solid Waste Management Plan shall not constitute the basis of any contract which may be concluded for the exchange of notes. The recipient must rely on its own enquiries and on the terms and conditions contained in any agreement, when and if finally executed, subject to such limitations or restrictions as may be specified therein. AECOM will devote normal professional efforts compatible with the time and budget available in performing the Services. AECOM's findings represent its reasonable judgments within the time and budget context of its commission and utilising the information available to it at the time of performing the Services. AECOM are making projections/recommendations based upon limited information that has been made available to them; such projections/recommendations are subject to many factors that are beyond the control of AECOM; and AECOM thus make no representations or warranties with respect to such projections/recommendations and disclaim any responsibility for the accuracy of any estimates, projections and recommendations. Any opinion expressed by AECOM concerning the revenue, capex and opex is based on the generally accepted engineering practice in effect at the time of the assignment and information that has been supplied to AECOM by the Client and others in connection with the assignment. Any indication of cost would be in the form of an ‘order of magnitude estimate’, which should only be considered as an early indication of cost and in no case be considered as the actual costs. Such opinions are subject to risks and uncertainties that are beyond the control of AECOM. The passage of time may result in changes in technology, economic & market conditions, competitive factors, site variations, new products, company’s policy or regulatory provisions which would render the opinions inaccurate. Thus AECOM makes no representations or warranties with respect to such opinion or recommendation and disclaim any responsibility for the accuracy and completeness of any opinion or estimates.
